The debug builds already have quite a bit of performance overhead. It
might be desirable to change this RFC to have a similar tri-state as
the MPI parameter checking:
- compiled out
- compiled in, always check
- compiled in, use MCA parameter to determine whether to check
Adapting that to this RFC, perhaps something like this:
- compiled out
- compiled in, always convert standard send to sync send
- compiled in, use MCA parameter to determine whether to convert
standard -> sync
And we can leave the default as "compiled out".
Howzat?

Hi all,
How about exposing this functionality as a run-time parameter that
is only
available in debug builds? This will make debugging easier and won't
impact the performance of optimized builds. Just an idea...
